Answer:
9. 0.016 pounds (Malika - 1.032; Adrian - 1.016)
10. The best inference I can create that is supported by this data set is that Malika put more potato salad per container (1.032) than Adrian did (1.016).
Step-by-step explanation:
Question #9 asks about the difference between mean masses, so what we need to do first is add up each of the value, and then divide them by 5.
Malika:
(1.1 + 1.08 + 1.05 + 0.95 + 0.98)/5
(2.18 + 2 + 0.98)/5
(3.16 + 2)/5
5.16/5
1.032 is the mean mass for Malika's containers.
Adrian:
(1.3 + 1.21 + 0.79 + 0.9 + 0.88)/5
(2.51 + 1.69 + 0.88)/5
(2.51 + 2.57)/5
5.08/5
1.016 is the mean for Adrian's containers.
Then, subtract the two means.
1.032 - 1.016
The difference between the means is 0.016 pounds (#9's answer).
With that information, we can quickly answer #10. For example, I've put:
The best inference I can create that is supported by this data set is that Malika put more potato salad per container (1.032) than Adrian did (1.016). (My answer for #10.)
